+ update release notes
+ minor build-fixes, mostly to test-package scripts
+ modify check for sizeof(wchar_t) to ensure it gives useful result
when cross-compiling.
+ drop assumption in configure script that Cygwin's linker is broken.
+ define NCURSES_BROKEN_LINKER if the broken-linker feature is used,
to simplify configure-checks for ncurses-examples.
+ reassert copyright on ncurses, per discussion in ncurses FAQ:
https://invisible-island.net/ncurses/ncurses.faq.html#relicensed
+ modify comparison in make_hash.c to correct a special case in
collision handling for Caps-hpux11
+ add testing utility report_hashing to check hash-tables used for
terminfo and termcap names.
+ fix a missing prototype for _nc_free_and_exit().
+ update a few comments about tack 1.07
+ use an awk script to split too-long pathnames used in Ada95 sample
programs for explain.txt
+ modify configure script to remove deprecated ABI 5 symbols when
building ABI 6.
+ add symbols _nc_Default_Field, _nc_Default_Form, _nc_has_mouse to
map-files, but marked as deprecated so that they can easily be
suppressed from ABI 6 builds (Debian #788610).
+ comment-out "screen.xterm" entry, and inherit screen.xterm-256color
from xterm-new (report by Richard Birkett) -TD
+ modify read_entry.c to set the error-return to -1 if no terminal
databases were found, as documented for setupterm.
+ add test_setupterm.c to demonstrate normal/error returns from the
setupterm and restartterm functions.
+ amend cleanup change from 20110813 which removed redundant definition
of ret_error, etc., from tinfo_driver.c, to account for the fact that
it should return a bool rather than int (report/analysis by Johannes
Schindelin).
